ZR NR series Radial Type
ZR NR Series (Radial type)
Disk type general use ZR type (Low voltage) and NR type (Medium/High Voltage) are for protection of electronics and control
eqiupments from surge and noise.
1. Features
Superior nonlineality of voltage to maintain low limiting voltage.
Symmetry V-I characteristics to be applicable for +/- surge and AC circuit.
Small in size, high in surge endurance to be stable for repetitive surges.
Quicker response and sharper cut-off compared with discharge type protector.
Low temperature coefficient.
Wide applicable voltage range.
High reliability.
2.Application
Protection of semiconductors from surge voltage.
Protection of circuit and lines from induced lightening surge.
Protection from relay noise.
Voltage stabilization.
3.Qualification
MNR disk type is qualified for UL1414, 1449 and CSA C22.2, to be available for exporting. Also international standard, ISO-9001
qualification is obtained.
4.Patents
Japanese Patent
55-48442 and several patents are registered.
